Help me please? I only have these two questions that I can't answer!
1:
Mark and Nancy are making punch for a party and are using two types of juice: pineapple and papaya. The total number of quarts must be more than 9 but less than 15. They should use at least 4 quarts of each type. We want to find out how many quarts of each juice they should buy.
First graph the system below and describe the shape of the solution area.
x + y ≥ 9; x + y ≤ 15; x ≥ 4; y ≥ 4

Pick one ordered pair solution for this problem and tell what each number represents.

The shape is a trapezoid. x can represent the number of quarts of pineapple or papaya, so just pick one. If x is the pineapple, then y is the papaya. Solutions to this problem lie inside of the trapezoid.
(6,6) clearly lies inside the trapezoid, so a possible solution is 6 quarts of each for the punch.
